It is Well known that veseeis prepef by screws have a shaft tunnel er *fmzmels built through the center of the cargo home through which the shafting tm'nsmifis the power frem the prime mover t0 the prc peller, and that these tunnels encreaci'r upen, 3111i deduct censiderably from the held ca pacity, as Well as obstructin and breaking up the stowage of cargoes end interfering in the case of bulk cargces such. as coal, sulfur and ores, with she grab buckets used in ischerging these cargoes In some case, the broken stcwage thus causer is so considerable, that ewners and shipbuilders have reserted $0 the expeclient cf fitting a Watee tight pietform, or Seek, fie inelese the shefis in a separate held with its atteneiant ices in cargo capacity. These tunnels, em} izi ris alternative of fitting Watertight platferm or cree resulii in the ac'idition of much maeerie t0 the vessels sbru'ceere and in ercier therefore to lighten eeustruetica and to remove ihe objectionable features of broken sfie'wage, end else the ebsfiructien eeuse i by the tunnels to the use of the grabor other cargo discharging hnpiemcnes We have disceverecl that with certain types 0? prime movers it is possible in areenge and construct What We term bilge tunnels main em Seriei He.
